Troubleshooting

Symptom	Possible Cause	Corrective Action
Engine misfire	Spark plugs, coils, fuel injectors	Check spark plugs and coils; test fuel injectors; scan for codes.
Transmission slipping	Low fluid, worn clutches	Check fluid level and condition; perform pressure test; scan TCM.
Brake vibration	Warped rotors, stuck calipers	Measure rotor thickness and runout; inspect caliper slides.
Electrical issues	Battery, alternator, grounds	Load test battery; check alternator output; clean ground connections.
A/C not cooling	Refrigerant leak, compressor	Check refrigerant pressure; leak test system; test compressor clutch.

Reset: Use scan tool to clear adaptive memory after repairs.
